Treatment options and typical costs
Property Inspection for Breeding Sites
$0–$150 (often bundled with a first treatment)
Around Monroe, a good inspection sets expectations too: a yard that backs onto a wetland won't respond like a dry cul-de-sac, and the pro should tell you that up front.

- Best for
- Every yard; finds where mosquitoes actually breed
Source Reduction and Larviciding
$75–$150 per visit
Larvicide hits mosquitoes before they can fly, which is why pros in Monroe build every plan around it. Adult spraying is the follow-up, not the fix.
- Time
- 45–90 minutes
- Best for

$50–$150 per follow-up visit; $350–$900 per season bundled

- Best for
- Shaded yards with shrubs, ivy, and dense landscaping

The weekly water walk.
- Tree holes: fill them with sand. - AC drip lines and downspouts: make sure water drains away. - Pet bowls: refresh daily. - Birdbaths: change the water twice a week. - Tarps and covers: pull them tight so water runs off. - Toys and buckets: store them upside down. - Saucers and pots: empty them or add sand. - Gutters: clear leaves so water drains.
Avoiding bites.
- Timing: tiger mosquitoes bite by day; house mosquitoes at dusk. - Screens: repair holes in window and door screens. - Fans: a patio fan keeps weak-flying mosquitoes away. - Clothing: long sleeves and pants help at dusk. - Repellent: DEET, picaridin, IR3535 or oil of lemon eucalyptus.
Low-cost ways to cut mosquitoes.
- Lights: yellow bug lights attract fewer insects to the porch. - Trimming: thin out dense shrubs and tall grass. - Pumps and fountains: moving water breeds far fewer mosquitoes. - Mosquito fish: they eat larvae in ornamental ponds. - Mosquito dunks: Bti tablets kill larvae in rain barrels and ponds.
Mosquito or look-alike?
- Mosquitoes: slim, long legs, and a needle-like mouth. - No-see-ums: tiny biting gnats near marshes. Screens need a finer mesh. - Non-biting midges: swarm near water at dusk. Harmless, just annoying. - Crane flies: look like giant mosquitoes. They don’t bite.
When a bite needs a doctor.
Spreading swelling or an infected-looking bite needs a check too. See a doctor for high fever, stiff neck or confusion. About one in five get a fever, headache or body aches. Most people infected with West Nile virus never feel sick. Most bites just itch for a few days.
Protecting your pets.
Refresh pet water bowls daily; with about 54 inches of rain a year in Monroe, bowls and plant saucers refill themselves. Keep animals inside until a yard treatment dries. Talk to your vet about year-round prevention. Heartworm reaches dogs through mosquito bites, and cats can get it as well; Monroe's season runs roughly May into December, so year-round prevention is the usual advice.
What a treatment visit looks like.
Most plans repeat every three to four weeks. Then they spray shady shrubs, where adults rest. Larvicide goes in water you can't drain. They dump or treat standing water. The tech walks the yard first. A visit usually takes 20 to 45 minutes.
Rain barrels and ponds.
- Pool covers: drain standing water after rain. - Tarps: shake out any that hold rainwater. - Gutters: clear them so water drains away. - Bird baths: change the water every few days. - Ponds: fish and moving water keep larvae down. - Barrels: cover openings with fine mesh.

What's your biggest concern about mosquitoes?
When to call for help
early in the season, before the first big wave. Ponds, drains and dense shrubs are hard to handle yourself. Call if bites still keep you indoors. Dumping water should come first.
What you can do yourself
The biggest win is free: dump standing water every week. Use repellent and run a fan on the patio. A pro adds larvicide for water you can't drain. They also spray where adults rest, every few weeks.
